# DC 8004 - Paralysis agitans

Rated under § 4.124a. Body system: Neurological Conditions and Convulsive Disorders.

## Rating criteria

| Rating | Criteria |
| --- | --- |
| 30% | Minimum rating |

## Notes

- Note: It is required for the minimum ratings for residuals under diagnostic codes 8000-8025, that there be ascertainable residuals. Determinations as to the presence of residuals not capable of objective verification, i.e., headaches, dizziness, fatigability, must be approached on the basis of the diagnosis recorded; subjective residuals will be accepted when consistent with the disease and not more likely attributable to other disease or no disease. It is of exceptional importance that when ratings in excess of the prescribed minimum ratings are assigned, the diagnostic codes utilized as bases of evaluation be cited, in addition to the codes identifying the diagnoses.

# Paralysis Agitans (Parkinson's Disease) — VA Diagnostic Code 8004

*Neurological Conditions and Convulsive Disorders · 38 CFR § 4.124a*

## Understanding This Rating

Paralysis agitans is rated by the VA under **Diagnostic Code 8004**, part of the neurological conditions and convulsive disorders group in **§ 4.124a**.

## Available Rating Level

Under Diagnostic Code 8004, the VA assigns a single defined level:

| Rating | What It Reflects |
|--------|------------------|
| **30%** | Minimum rating |

The 30% figure is the prescribed **minimum rating**. When the VA assigns a rating in excess of this minimum, it does so by citing the additional diagnostic codes used as the basis for that higher evaluation, alongside the code identifying the diagnosis itself.

## What the VA Looks For

- **Ascertainable residuals.** For the minimum ratings under diagnostic codes 8000–8025, there must be ascertainable residuals. This is a required condition for the rating.

- **How residuals are assessed.** Determinations about residuals that cannot be objectively verified — such as headaches, dizziness, or fatigability — are approached on the basis of the diagnosis recorded. Subjective residuals are accepted when they are consistent with the disease and are not more likely attributable to another disease or to no disease.

- **Citing the basis for higher ratings.** The notes emphasize that it is of exceptional importance that, when ratings in excess of the prescribed minimum are assigned, the diagnostic codes used as the bases of evaluation are cited in addition to the codes identifying the diagnosis.
